Summer is here! ☀️ 🧘‍♀️ And a whole bunch of yogis took over Times Square to mark the Summer Solstice on Sunday. (Say that 3 times fast!) Swipe through to see the pics! 👉 So what is the summer solstice? The first day of summer 2021 is June 20 at 11:32 p.m. EDT. It's often called the longest day of the year because it's the day with the most daylight (every "day" has 24 hours). 🌞 For many cultures around the world, the first day of summer is welcomed with celebrations and rituals that recognize the sun's importance to human life. Summer solstice observations take many forms around the world. 🥵 While it marks the first day of summer, the real heat is still to come. On average, there is a one-month lag between the solstice and peak summer temperatures. That's why July is almost always the hottest month of the year in most locations. 📸: Timothy A.
